from the corresponding open chain (pentafluorobenzene)sulfonamides 4 by complementary solid-liquid phase transfer catalysis (SL-PTC) and homogeneous protocols. The cyclization step proceeds through the intramolecular nucleophilic displacement of an aromatic fluorine atom.
通过互补的固-液相转移催化(SL-
PTC)和均相方案,由相应的开链(
五氟苯)磺酰胺4合成了含有
α-氨基酸单元的多官能化苯并[d] sultams 7和8。环化步骤通过芳族
氟原子的分子内亲核取代进行。
